You can't imagine the effort I have to put in to write a podcast episode (will be about moss). First of all, I have to understand everything myself so that I can then tell you all about it in three sentences in the most entertaining way possible.

Idea for a debugging script

This might already exist for FreeBSD, and if so.. let me know!

- 1) keeps record of OS core/default settings: loader.conf, rc.conf, sysctl.conf, devfs.rules, login.conf etc
- 2) keeps record of file checksum on those OS core files (similar to the app, tripwire)
- 3) mode which shows divergence on current state vs known-default state in configs (1) and checksums (2)
-4) mode which tracks the files and their change-sets over time, similar to a zfs snapshot but at a single file-level

Here's a demo of the mp3 glitching script I wrote about here: https://reillyspitzfaden.com/posts/2025/04/databending-part-3/

I added a batch script so I can take in a bunch of folders of .wav files, use ffmpeg to convert them to mp3 (and try out different bitrates), glitch them, re-encode those as .wav (easier to work with), and then clean up all the intermediate mp3s.

In less than 18 hours, including a solid 12 hours (at least) of downtime, I have gone from concept to 90% functional prototype of a creative rPi project, thanks to aus.social allowing quick and easy downloads, jq, an obscure CUPS driver project, and an intimate knowledge of scripting.

Feeling very accomplished.

Today I found that bash uses dynamic scoping, not lexical scoping. So if you have a

function inner() {
echo "$x"
}

it will go up the call stack to find the first x defined as

local x

in any caller and print it. Pity (add more swearwords here) . There is a reason why emacs lisp is being converted to lexical scoping despite having decades of dynamic binding history.

I added some more cool things to my grimoire! https://reillyspitzfaden.com/code/#grimoire

I have interactions on Mastodon/Bluesky coming in as webmentions, and that's nice, but other sources get lost in the shuffle, so I have a script here (https://github.com/reillypascal/personalsite-ssg/blob/main/webmentions.py) that filters out all the ones where "wm-source" contains "https://brid.gy/," which is super helpful.

Measuring times in bash.

- time: put in front of your command and it spits out some timing millisecond resolution, but you cannot capture the number to use it elsewhere
- starttime=$(date +%s%N) and same for endtime: this is expensive in the millisecond range, because the external command, date is run
- printf "%(%s)T" has only seconds resolution

Now I found "$EPOCHREALTIME". But set LC_NUMERIC=en first or lose.
